Historical note: Only 10 of these unusual locomotives were built, all for the NSW Railways, and were Clyde-EMD's attempt to produce a locomotive of similar configuration to the Goodwin ALCo DL-500. They have a driving cab at each end, one with the familiar bulldog nose. They were powered by the EMD 16-567C engine rated AT 1,800HP, had a C-C wheel arrangement, were fitted with dynamic brakes, buffing plates, and automatic couplers. They were the first locos on the NSW system to have 5 digit numbers, being designated the 421 class. Class leader 42101 entered service on December 22, 1965, and 42110 was officially handed over on July 25, 1966. The AJ16 Cs were not as reliable as the older A7s and were criticised by crews for rough riding. Various combinations of springs and shock absorbers were tried on the trucks to cure the problem, but to no avail. The trucks on the AJ16 Cs were of a different design from those used on the A7s. The AJ16 C used a newer Flexcoil type with unequal axle spacing, which may have had some bearing on the problem. All have been withdrawn and bought by several private operators, so these rare locos will be seen well into the next century.
